Alto RMX2408DFX

*This is the last one of these amps as it's now a discontinued model.

Light, rugged and powerful.

The Alto RMX2408DFX is a 2000 watt powered mixer with EQ and effects. It features 2000 watts of Class D power. Class D amplification makes the RMX2408DFX not only powerful but also incredibly light compared to other solutions. Very versatile output section: 2 x 1000w @ 8ohms, or 2 x 500w @ 4ohms + 1 x 1000w @ 8ohms, or 4 x 500w @ 4ohms.

The RMX2408DFX also features a useful array of tools including 8 XLR jacks with phantom power, 8 Line jacks and stereo RCA. This means that whether you're plugging in guitars, mics, keyboards or even an iPod for playback between sets, you're covered with the RMX2408DFX .

Once everything is connected, there's a full on-board digital effects processor and 3-shelf EQ on each mono and stereo channel so you can dial in the perfect sound at any venue. A 24-bit, built-in Alesis DSP effects engine supplies ample options for sweetening including Hall, Room, Vocal & Plate reverbs, Mono & Stereo delay (max delay time 650ms), Chorus, Flanger & Reverb modulations, Reverb+Delay, Reverb+Chorus and Reverb+Flanger combinations. 256 different Alesis DSP presets provide ample options for any situation. When the gig is done, inset, molded handles on both ends make it super easy to transport.
